When did everyone start potty training? We are going to start trying!

My daughter is 15 months & has been showing interest. I feel like it's to soon, but I'm gunna try but not force it on her.

I started at 21 months and she was completely potty trained by 22 months. been accidents free since November! ! just depends when they are ready:(

I started at 2... however it really just has to be their decision or it won't stick.
